Additional Context
Please add any additional context about the error here

No files, tests, or entry points are named. Start by tracing the Gemini provider's error handling from the reported 429 RESOURCE_EXHAUSTED response, and compare it with the path that produces “Unknown error.” Done means the quota failure is represented distinctly rather than losing the provider's useful error details.
